Summary - HP Compaq dx6050 MT Configuration Manual

The HP Business PC dx6050 will not support future Athlon XP processors with front-side buses that
operate at a 400 MHz.
HP offers the following recommendations for maximizing performance:
• Dual-channel–While it is possible to configure single-channel main memory, HP recommends the
dual-channel configuration, which doubles memory bandwidth.
• Matching DIMMs–When configuring dual-channel memory, HP strongly recommends using DIMMs
that are matched in size and speed.
• If DIMM speeds are mismatched, memory runs at the speed of the slower DIMM.
• If the DIMMs are different sizes, then part of the memory configuration is dual-channel and part is
single-channel.
Note
See the Appendix for more information on the impact of using mismatched
DIMMs.
• Memory size–Depending on configuration, memory performance can differ between desktops with
the same total memory size. For example, a desktop with two 128MB DIMMs may out-perform a
system with a single 256MB DIMM (because the dual-channel configuration doubles memory
bandwidth). Again, HP recommends the dual-channel configuration.
• Graphics driver–HP recommends using the graphics driver supplied with the HP Business PC
dx6050. Using an alternative driver may impact system performance (as shown in the Appendix).

Summary

The NVIDIA GeForce4 MX graphics integrated into the HP Business PC dx6050 automatically receive
an allocation of up to 64 MB of DDR main memory.
The HP Business PC dx6050 supports single-channel and dual-channel configurations. Performance
tests carried out by HP indicate that a dual-channel memory configuration can achieve significant
performance gains. Some care is required when configuring memory; mismatched DIMMs or the use
of an alternative graphics driver can degrade graphics or system performance.
Simple, yet powerful and reliable, the HP Business PC dx6050 is an excellent investment for today's
small to medium business customers.
